Streets of London

Quantum technology is an amazing thing, for it can be used for many applications, improving our lot beyond the current scope. And though the technology is still at a very early stage, there is little doubt things are moving ahead fast.

One use case of this is quantum sensing. By applying photonic systems or solid-state systems, quantum sensors can have far-reaching effects in microscopy, positioning systems, communication technology, electric, and magnetic field sensors.

According to Kai Bongs, a professor at the School of Physics and Astronomy, the University of Birmingham and principle investigator of the UK Quantum Technology Hub Sensors and Timing: “Some have said that what lies below one metre under the streets of London is less well-known than Antarctica.”

This is an interesting fact, and one the wizardry of quantum sensors may soon be addressing.

“There are thousands of mine shafts in the UK, often two metres or less across, and if the top of the shaft is five metres or more below ground then they can’t currently be detected,” said George Tuckwell of geoscience, engineering and environmental consultancy firm RSK, a company leading the Gravity Pioneer project that is funded by Innovate UK, which brings together industry and academic experts aiming to develop the first commercial quantum technology Gravity program. “But the new sensor will be able to see most of them.”

This is great news for the sector because after the cause comes the effect. But what is this effect?

Startups, that’s what, springing up with their own unique ideas on how to solve some of the most pressing concerns in the space. Yet not only them. Older sensor companies too, have been around for a long time and are jumping at the opportunity to design and manufacture quantum sensors with little or no problem in adapting their technology to the changing tide.

Like always, TQD will now list a dozen or so companies and startups with their fingers in the quantum sensor pie.

If you want to learn more, we’ve compiled the most comprehensive list of the top quantum computing companies available!



Co-founded by Bill Biggs as Lambda Instruments Corporation back in 1971 to design and build sensors along with other products, it changed its name to LI-COR, Inc. in 1978.

LI-COR is a global leader in developing innovative, high-quality instrumentation for biotechnology and environmental technology. Based in Lincoln, Nebraska, the company is now fifty-years-old and still going strong.
